VIEWING MANIPULATION

 

    SX - SCREEN X ROTATION

This shortcut rotates the model about the screen X-axis, where the X-axis is parallel to the horizontal edge of the screen.  When the user selects this command, DSI displays a ruler bar on the right side of the screen.  Moving the cursor up or down causes the model to rotate; tick marks represent 20-degree rotation increments.  Clicking the left mouse button stops the rotation.

 

    SY - SCREEN Y ROTATION

This shortcut rotates the model about the screen Y-axis, where the Y-axis is parallel to the vertical edge of the screen.  When the user selects this command, DSI displays a ruler bar on the right side of the screen.  Moving the cursor up or down causes the model to rotate; tick marks represent 20-degree rotation increments.  Clicking the left mouse button stops the rotation.

 

 SZ - SCREEN Z ROTATION

This command rotates the model about the screen Z-axis, where the Z-axis is perpendicular to the plane of the screen.  When the user selects this command, DSI displays a ruler bar on the right side of the screen.  Moving the cursor up or down causes the model to rotate; tick marks represent 20-degree rotation increments.  Clicking the left mouse button stops the rotation.

 

 VX - VIRTUAL X ROTATION

This command rotates the model about the global X (the X-axis is as displayed in the coordinate system at the lower left side of the screen).  When the user selects this command, DSI displays a ruler bar on the right side of the screen.  Moving the cursor up or down causes the model to rotate; tick marks represent 20-degree rotation increments. Clicking the left mouse button stops the rotation.

 

 VY - VIRTUAL Y ROTATION

This command rotates the model about the global Y (the Y-axis is as displayed in the coordinate system in the lower left hand corner of the screen).  When the user selects this command, DSI displays a ruler bar on the right hand side of the screen.  Moving the cursor up or down causes the model to rotate; tick marks represent 20-degree rotation increments.  Clicking the left mouse button stops the rotation.

 

 VZ - VIRTUAL Z ROTATION

This command rotates the model about the global Z (the Z-axis is as displayed in the coordinate system in the lower left corner of the screen).  When the user selects this command, DSI displays a ruler bar on the right side of the screen.  Moving the cursor up or down causes the model to rotate; tick marks represent 20-degree rotation increments. Clicking the left mouse button stops the rotation.

 

 TOP VIEW

This command automatically displays the model from the TOP or XY-plane.

 

 SIDE VIEW

This command automatically displays the model from the SIDE or XZ-plane.

 

 REAR VIEW

This command automatically displays the model from the REAR or YZ-plane.

 

 ISOMETRIC VIEW

This command automatically displays the model form the ISOMETRIC (60 Degree Isometric) point of view.

 

 FREE ROTATION

The Freehand Rotation (FREROT) command is a combination of SX and SY.  Moving the mouse up/down manipulates SX.  Moving the mouse left/right manipulates SY.  Moving the mouse diagonally combines the movements of both commands.  Clicking the left mouse button stops the rotation. This function can also be activated by pressing Control and the left mouse button.

 

 PAN

This command translates the model by following the movement of the cursor.  If the cursor is moved off the screen, the cursor reappears at the center of the screen.  Clicking the left mouse button stops the pan. This function can also be activated by pressing Control and the middle mouse button.

 

 CURSOR ZOOM

The user picks a point about which to zoom. The model is centered about this point and the User may move the cursor up or down to zoom in and out. This function can also be activated by pressing Control and the right mouse button.

 

 WINDOW ZOOM

The user defines the corners of the zoom window by positioning the cursor on the display screen. The user presses the left mouse button and drags the mouse diagonally down until the desired window size is reached. Release the left button. The section included in the window is displayed in full screen.

 

 FREE HAND ZOOM

The user defines the area of zoom window by clicking and holding the left mouse button in the display area and drawing a circle around the interested area. When the left button is released, the area that had been circled is displayed full-screen.

 

 FILL

This command rescales the model to include all entities belonging to parts that are currently turned on.  FILL automatically zooms in or out until the model fits the viewing area of the screen.

 

 ACTIVE WINDOW

This command allows the user to isolate a portion of the displayed geometry/model for more detailed viewing or editing. For a detailed description, see section 9.1.16 VIEW/ACTIVE WINDOW.

            

 REDRAW

DSI is currently designed to update the screen after each command.  Occasionally, the use of specific commands requires that images be updated with an additional step

(e.g., when the user operates the dynamic zoom at the same time that the element normals are displayed, he or she must activate the REDRAW command to resize the arrows that represent the element normals).

   

 CLEAR

Allows the user to remove the highlighted entities from the screen such as those that are made with the commands SHOW LINE, BOUNDARY CHECK, ID ELEMENT, DEFINE TITLE, etc.

 

2-12b   CLEAR NODE

Clear the display of connecting nodes

 

2-12c   CLEAR ELEMENT

Clear the display of connecting elements

 

   IDENTIFY NODE

This function enables the user to identify any node.

 

   IDENDFIY ELEMENT

This function enables the user to identify any element.

 

   DISTANCE BETWEEN TWO NODES

This function enables the user to calculate the distance between two nodes.

 

   ANGLE BETWEEN THREE NODES

This function enables the user to measure the angle between two vectors formed by three nodes.
